The main object of this invention is to provide a window frame having sashes which are slidable and which may be selectively hinged so that the sashes may be swung into a room to permit the cleaning of both sides of the window panes without danger of injury to the person cleaning the window, who would ordinarily have to sit upon the sill of the window frame in order to clean the window.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure l is a perspective view of the window frame, showing the window sashes and the hinge mechanisms on the sashes.

Figure 2 is a cross sectional view taken through the window. frame and the window, showing one of the window sashes in hinged position, and the other window sash in released position.

Figure 3 is a sectional front elevational view of Figure 2, the section being taken on line 3-3 of Figure 2.

Figure 4 is a longitudinal sectional elevational view of a corner of the window frame, showing the detachable guide strip mounted in place thereon.

Referring in detail to the drawing, the numeral 10 indicates the sill of a window frame. This sill 10 has side beams 11 eX- tending upwardly from each of its ends.

These side beams 11 and a top board 12, with appropriate moulding, form a frame in which a normally raised window sash 13 and a normally lowered window sash 14 are slidable. The interior surface of the beams 11 are provided with a marginal slat 15 and an intermediate guide strip 16.

Each of the window sashes 13 and 14 is provided with a pyramidal recess 17 in a side of which one of the plate members 18 of a hinge is located. The complemental plate 19 of the hinge unit is pivotally secured to a hinge strap 20. The hinge plate 19 has a plurality of sleeves upon both of its sides and is provided with an extending ear 21 whose extreme end is formed into a sleeve 22 which retains a rod 23, the rod 23 coupling all the hinge units on one of the sashes 13 or 14. In the .illustration in Figure 1, the hinge units are shown to the number of two,both of which are joined by the rod 23. The hinge strap 20 may be readily detached from the hinge plate 19. The hinge plate 19 at the end engaging the hinge strap 20 has a sleeve 24 which is adapted to engage upon the hinge 'pin 25 extending upwardly 6o from the hinge sleeve 26 formed on the hinge strap 20, and is located in an elongated channel 27 formed in the slat 15 and guide strip 16 near their lower ends.

The hinge plates 18 and 19 are adapted to 65 fold one upon the other while the hinge plate 19 is rotated to projecting position by a resilient doubled finger 28.

The window sashes 13 and 14 are adapted to be slid between the slat 15 and strip 16 or, 70 when shifted to the lowered position, are adapted to be rotated within a room so that the outer surfaces of the window panes 29 and 30 may'be cleaned without danger of injury to the person cleaning the same. To permit the free ends of the sashes 13 and 14 to be removed and swung inwardly upon .the hinge pins 25, the guide strip 16 on the opposite side of the window frame is divided into two strip sections 31 and 32 which are 30 arranged end to end with an inclined jointure -33 provided to permit interlocking of the strip sections 32 and to prevent detachment of these two members while both window sashes are in upper position in the window frame. The free strip section 32 is supported at its lower end upon an arched iinger 34 whose curvature enters into a saddle 35 formed in the strip 32, as illustrated in Figure 4. The sashes 13 and 14 may be removed 90 and rotated inwardly into a room of which the window forms a part by first removing the strip 32, which is accomplished by pulling the lower end of the strip 32 seated upon the arched iinger 34 outwardly. This re- 95 moves the only impediment to the swinging of the outer and upper window sash 13. After this has been accomplished, the window which it is desired to rotate inwardly is brought to the lowered position in the frame *00 and, as the hinge plates 19 pass the channel 27, the hinge sleeves 24 attached to the plates 19 enter into said channel 27 and further downward movement of the window sashes 13 and 14 causes the opening in said hinge members 24 to receive the pins 25, thus hingedly connecting the hinge plates 19 and 18 to the strips 15 and 16 after which the windows may be swung into the room.

To release` the window from the hinge units so that it may be slid upwardly in the window frame, the hinge plates 19 on asingle sash are rotated into the pyramidal recesses 17 by manipulation of the rod 23 against the resiliency of the finger 28, as th-ese hinge plates 19 have been shifted to a position at the upper end of the channel 27 free and clear oi' the hinge pins 25.

It is to be noted that certain changes in form and construction may be made without departing from the spirit and scope of the invention.

I claim:

1. In a window, a frame, sashes slidable in said frame, said sashes having recesses therein, hinge pins on said frame, a complemental plate adapted to be rotated into said recesses, means for rotating said complemental plate out of said recesses, sleeves on the free end of Asaid plate, said sleeves being normally adapted to align with said hinge pins, and means connected to each pair of plates for urging said plates into said recesses.

2. In a window, a frame, sashes slidable in said frame, said sashes having recesses therein, hinge pins on said frame, a complemental plate adapted to be rotated into said recesses, a spring behind said complemental plate for rotating said complemental plate out of said recesses, sleeves on the free end of said plate, said sleeves being normally adapted to align vwith said hinge pins, and means connected to each pair of plates for urging said plates into said recesses. p v

3. Inga window, a frame, sashes slidable in said fra-me, said sashes having recesses therein, hinge pins on said frame, a complemental plate adapted to he rotated into said recesses, a spring behind said complemental plate for rotating said complemental plate out of said recesses, sleeves on the free end of said plate, said sleeves being normally adapted to align with said hinge pins, an ear projecting from said complemental plate and rigid with the same, and a rod connected to said ear for rotating a pair of said complemental plate members into said recesses to 4disalign the hinge sleeves of a pair of complemental plates from the hinge pins on the frame simultaneously.

4. In a window, a frame7 sashes on said frame slidable therewith, a series of `means on said sashes simultaneously operable for connecting said sashes rotatably to said frame, and complemental means on said LORENZ PESCI-IKES.
